Swoods53, I looked up the quilt on this site that you are talking about. It said original design, so I doubt there is a pattern. If there
was you probably would not have had a hard time finding it since it was just a couple years ago she posted her quilt on TQS. Do not
get discouraged. It is a wonderful quilt idea for a wedding present. Other similar options are available. I am posting a couple screenshots
that might help you make a very similar quilt. One book on Amazon has a picture of a heart quilt made in that style. Other patterns
and kits are offered by Whims a company that sells beautiful watercolor quilt kits. It would be easy to design and draft a heart idea on graph paper
and buy a kit with fabrics
from a place like Whims thats is designed for a different pattern and use those fabrics on your own drafted heart idea.
Let me know if you still would like more brainstormed ideas. I think you have a great idea going and if I can help point you in the right
direction I am more than happy to help do that. HelenW
